The explosion of an atomic bomb (M = 1 kg of plutonium 242Pu) produces one radioactive particle for each plutonium atom. Assuming that the winds uniformly mix these particles throughout the atmosphere, calculate the number of radioactive particles falling into a volume V = 1 dm3 of air at the Earth’s surface. The radius of the Earth is taken equal to R = 6•106 m.
